"Because it is written, Be ye holy; for I am holy." 1 Peter 1:16
The tempter's agency is not to be accounted an excuse for one wrong act. Satan is jubilant when he hears the professed followers of Christ making excuses for their deformity of character. It is these excuses that lead to sin. There is no excuse for sinning. A holy temper, a Christlike life, is accessible by every repenting, believing child of God.
